    Description

      Starting from 2.0.0, KafkaConsumer doesn't report records-lag if isolation.level is read_committed. The last version, where it works is 1.1.1.

      The issue can be easily reproduced in kafka.api.PlaintextConsumerTest by adding consumerConfig.setProperty("isolation.level", "read_committed") witin related tests:

      • testPerPartitionLagMetricsCleanUpWithAssign
      • testPerPartitionLagMetricsCleanUpWithSubscribe
      • testPerPartitionLagWithMaxPollRecords
